technical field

The utility model relates to the field of accumulators, in particular to a lead-acid accumulator.                     

Background technique

When designing many lead-acid batteries, lead terminals are used, and the lead terminals are first welded to the busbar, and then put into the slot and covered with a cover. However, this structure still cannot effectively prevent the deformation of the terminals, and if the terminals are deformed, the resistance will easily increase, which will affect the sealing effect between the terminals and the battery cover, thereby causing electrolyte leakage and affecting the normal use of the battery.

The upright block is connected with the support block through a connection block, the connection block is placed on the top of the upright block and the support block, the lower end of the support block is connected with the horizontal block, and the direction of the horizontal extension of the horizontal block Contrary to the direction of the connecting block, the upright block, the horizontal block and the connecting block are all provided with round holes;

The top of the middle cover is provided with a "convex"-shaped boss, and the two sides of the boss are respectively provided with through holes for receiving the connection block of the terminal. The boss is provided with a liquid injection hole, a pole Holes and polar post holes, the polar post holes are placed on the boss in two parallel rows, the liquid injection hole is placed between the two rows of polar post holes; one row of the polar post holes The post hole is on the same side as the two pole holes, and the position of the pole hole corresponds to the through hole on the horizontal block;

The upper cover is in a "convex" shape and fits with the boss.

Further, the distance between the polar post holes on the same side as the pole post holes and the liquid injection hole is greater than the distance between the other row of polar post holes and the liquid injection holes.

Further, the shoulder of the upper cover is provided with two fastening parts, and the two fastening parts extend vertically downwards and are respectively left-right symmetrical along the protruding part of the upper cover.

Further, the terminals are copper terminals.

The utility model changes the structure of the terminal, and the pole hole is covered by the upper cover, which avoids the corrosion of the terminal due to contact with sulfuric acid, and also avoids the deformation of the terminal. The terminal structure can meet various wiring requirements and is replaced by copper materials. Lead material improves the product grade and does not hinder the wiring and use of the primary battery. When installing, first put the pole group into the slot, cover the battery body, and then connect the copper terminal to the lead pole with an electric soldering iron.
